from the pvc sample, 1.0 g is cut into pieces of about 0.5 cm of length. the pieces are dissolved in 25.0 ml of thf using a ptfe magnetic stir bar obtained from dutsher (tested phthalate free). a complete dissolution of the pvc sample is obtained after stirring about 20 30 min. the internal standard is added to the preparation.

the commonly used phthalates include dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), benzyl butyl phthalate (bbp), di-2-(ethylhexyl) phthalate (dehp), dicyclohexyl phthalate (dchp), and di-isononyl phthalate (DINP) . the physical and chemical information of the above-mentioned phthalates are summarized in table 1.
determination of dialkyl phthalate esters in indoor air price,a study was conducted to evaluate concentrations of four specific phthalates dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), and di(2-ethylhexyl) phthalate (dehp) in the indoor air of both industrial and administrative sectors within the pvc manufacturing facilities.
- How accurate are phthalates and DEHT in PVC?
- An accurate method for 11 phthalates and DEHT in PVC was developed and validated. The developed method has high-order metrological quality. The developed method was successfully applied to analysis of real-life PVC products. Phthalates are mainly used as plasticizers in polyvinyl chloride (PVC).
- Can phthalate terephthalate be used as a higher-order reference method?
- In this study, we developed an accurate and simultaneous method for determination of 11 representative phthalates and a non-phthalate plasticizer (di (2-ethylhexyl) terephthalate, DEHT) in PVC as a higher-order reference method.
- Can phthalates be quantified in PVC medical devices?
- In order to adapt this method to the quantification of phthalates in PVC medical devices, the extraction step was completely changed and additional phthalates such as DiDP or DiNP proposed to be forbidden in France in medical devices , were added.
- What chromatographic conditions are used for phthalates eluted before DEHP?
- For all compounds eluted before DEHP, including DEHP, the chromatographic conditions used for the quantification of phthalates in medical devices are identical to those developed for the determination of the same compounds in cosmetics (same chromatographic column, same injection conditions, same solvent, same ISTD, etc.).
- Which non phthalate plasticizers are used in PVC medical devices?
- In order to identify and quantify other plasticizers, which are commonly used in PVC medical devices such as DEHP substitute, 5 non-phthalate plasticizers, most commonly found such as DINCH, ATBC, DEHT, DEHA and TOTM, were added to the method .
- What are the limits of detection for phthalates?
- The limits of detection for (DEP, DAP, BBP, DBP, DCHP, DHP, DEHP, DOP, DINP, and DIDP) were 0.02, 0.04, 0.01, 0.03, 0.02, 0.03, 0.03, 0.01, 0.08, and 0.10 mg L, respectively. HPLC-PAD; PVC toys; phthalates; ultrasonic extraction.
